    Abstract:
    We report a 15-year-old male patient with recurrent epileptic seizures for 12 years. Oral multiple drugs do not work well to his condition. MRI FLAIR scans revealed focal cortical dysplasia type II in the right parietal lobe. The diagnosis of the patient was drug-refractory epilepsy, FCD-related secondary epilepsy. According to the shape of the FCD lesion, electrodes were implanted in a tapered pattern along the bottom of the sulcus to completely destroy the focus. Magnetic resonance imaging at 6 months after surgery revealed that the FCD at the sulcus bottom was completely destroyed. After 26 months of follow-up, the patient had undergone no epileptic seizures, reaching Engel class I. For FCD that are located deep in the brain and adjacent to functional areas, craniotomy has a high risk. And stereoelectroencephalography-guided radiofrequency thermocoagulation may be a preferred treatment.
